About

Multiple center, single-arm, open-label, 12-month follow-up phase IV pragmatic clinical trial in men with unilateral prostate cancer meeting eligibility criteria for the drug (as per the European Economic Area (EEA) Marketing Authorisation) to assess the occurrence and dynamics of the time with toxicities (urinary incontinence Grade 2 and over and/or erectile dysfunction Grade 2 and over) in patients 12 months following TOOKAD® VTP.

Full description

This is a multiple center, single-arm, open-label, 12-month follow-up phase IV pragmatic clinical trial. Men with unilateral prostate cancer meeting eligibility criteria for the drug (as per the EEA Marketing Authorisation) will receive TOOKAD® VTP under general anesthesia. The primary objective is to assess the occurrence and dynamics of the time with toxicities (urinary incontinence Grade 2 and over and/or erectile dysfunction Grade 2 and over) in patients 12 months following TOOKAD® VTP. Prior to the TOOKAD® VTP, patients will undergo routine ultrasound examination in the operating room for morphometric description of the prostate and to facilitate accurate treatment guidance for the treatment with TOOKAD® VTP. Treatment will then be applied to the prostate gland as a hemi-ablation procedure designed to destroy the lobe of the prostate gland that contains the cancer. Afterwards, patients will be followed for 12 months with clinical evaluation, data collection on erectile and urinary functions at 1, 2, 3 6 and 12 months, using the Expanded Prostate Cancer Index Composite (EPIC), International Index of Erectile Function (IIEF) and International Prostate Score Symptom (IPSS) questionnaires on Quality Of Life (QOL) and Prostate Specific Antigen (PSA) testing at 3, 6 and 12 months.

The clinical follow-up of patients will follow local standard of care processes, based on recommendations in the European Summary of Product Characteristics (SmPC).

This study is a phase IV pragmatic trial using optimal dose of TOOKAD® and optimal light-energy level conditions that were determined during development and approved by the European Commission.

Inclusion criteria

• Men over 18 years of age with a life expectancy ≥ 10 years

• Clinical stage T1c or T2a,

• Gleason Score ≤ 6, based on high-resolution biopsy strategies

• 3 positive cancer cores with a maximum cancer core length of 5 mm in any one core or 1 -2 positive cancer cores with ≥ 50 % cancer involvement in any one core or a PSA density ≥ 0.15 ng/mL/cm3.

• PSA ≤ 10 ng/mL

• If the patient is sexually active with women who are capable of getting pregnant, he and/or his partner should use an effective form of birth control to prevent getting pregnant during a period of 90 days after the VTP procedure.

• Signed Informed Consent Form

Exclusion criteria

GENERAL EXCLUSION CRITERIA :

• Unwillingness to accept the treatment;
• Any previous prostatic interventions where the internal urinary sphincter may have been damaged, including trans-urethral resection of the prostate (TURP) for benign prostatic hypertrophy.
• Participation in another clinical study involving an investigational product within 1 month before study entry;
• Inability to understand the informed consent document, to give consent voluntarily or to complete the study tasks, especially inability to understand and fulfill the health-related QOL questionnaire;
• Subjects in custody and or residing in a nursing home or rehabilitation facility;
• Biopsy proven locally advanced or metastatic prostate cancer.

SURGERY AND OTHER TREATMENT-RELATED CONDITIONS OF EXCLUSION

• Any condition or history of illness or surgery that in the opinion of the investigator might affect the conduct and results of the study or pose additional risks to the subject or any medical condition that precludes the administration of a general anaesthetic or invasive procedures.
• Hypersensitivity to the active substance or to the excipient (mannitol)
• Current or prior treatment for prostate cancer.
• Patients who have been diagnosed with cholestasis.
• Current exacerbation of rectal inflammatory bowel disease.
• Anticoagulant medicinal products and those that decrease platelet aggregation (e.g. acetylsalicylic acid) should be stopped at least 10 days before the procedure with TOOKAD. Medicinal products that prevent or reduce platelet aggregation should not be started for at least 3 days after the procedure.

TOOKAD VTP

Experimental group

Description:

TOOKAD is administered as part of focal VTP under general anaesthetic. TOOKAD® VTP consists of the combination of a single, 10-minute IV infusion of TOOKAD® at the dose of 3.66 mg/kg, followed by the illumination of the zone to be treated with a 753-nm laser light delivered through transperineal interstitial optical fibers at a power of 150 mW/cm and light energy of 200 J/cm applied over 22 minutes and 15 seconds.

Treatment:

Drug: TOOKAD VTP
